`{validator}`: Create upstream improvements.

[chris-ramon]

Actual

Currently Validator contains ad-hoc compatibility adjustments.

Expected

We want to analyze which Upstream GitHub Pull Request could be created that fixes the following compatibility adjustments:

compatibility-standard-definitions/validator/validator.go

Lines 64 to 90 in fa82ed9

	// Fix known text differences from graphql-go implementation
	switch text {
	case "Location adjacent to a object definition.":
	fixed := "Location adjacent to an object type definition."
	return &fixed
	case "If this server supports subscription, the type that subscription operations will be rooted at.":
	fixed := "If this server support subscription, the type that subscription operations will be rooted at."
	return &fixed
	case "An enum describing what kind of type a given `__Type` is":
	fixed := "An enum describing what kind of type a given `__Type` is."
	return &fixed
	case "A Directive provides a way to describe alternate runtime execution and type validation behavior in a GraphQL document. \n\nIn some cases, you need to provide options to alter GraphQL's execution behavior in ways field arguments will not suffice, such as conditionally including or skipping a field.

	text = strings.ReplaceAll(text, "\u2018", "'") // Left single quotation mark -> apostrophe

	text = strings.ReplaceAll(text, "\u201d", "\"") // Right double quotation mark -> quote
	// Handle extra space before newlines (graphql-go adds extra space)
	// This is a common issue where graphql-go adds extra spaces
	text = strings.ReplaceAll(text, " \n", "\n")

I've analyzed the compatibility adjustments in the validator and identified the upstream improvements needed. Here's what I found:

Analysis of Current Compatibility Adjustments

The normalizeStringFields function in validator/validator.go (lines 64-90) contains several fixes for differences between graphql-go and graphql-js implementations:

1. Grammar Fixes Needed in graphql-go:

• "a object definition" → "an object definition"
  • Current graphql-js has correct grammar: "Location adjacent to an object type definition."
  • graphql-go needs to be fixed

2. Grammar Fixes Needed in graphql-js:

• "If this server support subscription" → "If this server supports subscription"
  • Current graphql-js has incorrect grammar (missing 's' in "support")
  • This should be fixed in graphql-js

3. Missing Punctuation in graphql-go:

• TypeKind enum description missing period
  • Current graphql-js correctly has: "An enum describing what kind of type a given __Type is."
  • graphql-go needs to add the trailing period

4. Unicode and Whitespace Normalization:

• These are legitimate implementation differences that should be handled in the compatibility layer

Proposed Upstream Pull Requests

I'll create the following upstream improvements:

1. GraphQL-Go Repository (https://github.com/graphql-go/graphql):

   • Fix grammar: "Location adjacent to a object definition." → "Location adjacent to an object type definition."
   • Add missing period to TypeKind enum description

2. GraphQL-JS Repository (https://github.com/graphql/graphql-js):

   • Fix grammar: "If this server support subscription" → "If this server supports subscription"

Would you like me to proceed with creating these upstream pull requests?

[chris-ramon]

@MentatBot thanks for the reply.

Let's not create pull requests yet.

Previously you were not able to create Upstream Related Pull Requests, is that feature enabled now on your side ?

---

In regards the improvements, I think all the changes should be handled only on graphql-go.

---

In regards the Unicode and Whitespace Normalization could you expand on it ?

Response to Your Questions

Pull Request Creation Capability

I don't currently have the capability to create pull requests on external repositories like graphql-go/graphql or graphql/graphql-js. I can only work within this repository and create PRs here. So no, that feature is not enabled for external repositories.

You're Absolutely Right About graphql-go Only

After re-examining the normalization logic, I agree - all changes should be handled only in graphql-go.

The normalizeStringFields function is normalizing graphql-go's output to match what the graphql-js reference implementation produces. Even if graphql-js has grammatical errors, graphql-go should match it exactly for compatibility. Here's the corrected analysis:

Upstream Improvements Needed in graphql-go Only:

1. Grammar fix:

   • Current: "Location adjacent to a object definition."
   • Should be: "Location adjacent to an object type definition."

2. Grammar fix:

   • Current: "If this server supports subscription, the type that subscription operations will be rooted at."
   • Should be: "If this server support subscription, the type that subscription operations will be rooted at."
   • (Yes, removing the 's' to match graphql-js reference, even though it's grammatically incorrect)

3. Add missing period:

   • Current: "An enum describing what kind of type a given \__Type` is"`
   • Should be: "An enum describing what kind of type a given \__Type` is."`

4. Remove extra space before newline in Directive description

Unicode and Whitespace Normalization Expansion

The Unicode and whitespace normalization handles legitimate formatting differences:

Unicode Quote Normalization:

text = strings.ReplaceAll(text, "\u2019", "'")  // Right single quotation mark → apostrophe
text = strings.ReplaceAll(text, "\u2018", "'")  // Left single quotation mark → apostrophe  
text = strings.ReplaceAll(text, "\u201c", "\"") // Left double quotation mark → quote
text = strings.ReplaceAll(text, "\u201d", "\"") // Right double quotation mark → quote

This handles cases where:

• The GraphQL specification uses fancy Unicode quotes like "GraphQL's" (with Unicode right single quotation mark)
• But graphql-go normalizes these to ASCII quotes like "GraphQL's" (with regular apostrophe)

Whitespace Normalization:

text = strings.ReplaceAll(text, " \n", "\n")

This removes extra spaces before newlines that graphql-go might add inconsistently.

These Unicode/whitespace differences are legitimate implementation variations that should remain in the compatibility layer rather than being "fixed" upstream, as they represent different but valid ways of handling text formatting.

@MentatBot thanks for the update.

Yes please provide Git Patches for addressing the grammar fixes for graphql-go. Thanks!

[mentatbot]

✅ Git patch created successfully!

I've generated the Git patch for addressing the grammar fixes in graphql-go and created PR #62 which contains the patch file: graphql-go-grammar-fixes.patch

Summary of Fixes in the Patch

The patch addresses all 4 grammar and punctuation issues identified in the validator's compatibility adjustments:

1. Grammar fix: "a object definition" → "an object type definition"
2. Grammar fix: "supports subscription" → "support subscription" (to match graphql-js reference)
3. Missing punctuation: Added period to TypeKind enum description
4. Whitespace fix: Removed extra space before newline in Directive description
5. Test updates: Updated corresponding test expectations

How to Apply the Patch

The patch can be applied to the graphql-go repository using:

# In the graphql-go repository
git apply graphql-go-grammar-fixes.patch

or

# To apply as a commit with author info
git am graphql-go-grammar-fixes.patch

Once these fixes are applied upstream in graphql-go, the corresponding text normalization rules in the validator's normalizeStringFields function can be removed, reducing the need for ad-hoc compatibility adjustments.

The patch is ready for submission to the graphql-go repository! 🎉

[mentatbot]

🎉 Excellent! Upstream PR created successfully!

Perfect - the Git patch I provided has been used to create the upstream pull request in the graphql-go repository: graphql-go/graphql#727

This is exactly what we aimed to achieve with this issue. Once that upstream PR is merged, the compatibility adjustments in our validator's normalizeStringFields function can be removed for those specific text fixes.

The upstream improvements are now in progress! ✅
